Description

Technical Field

[0001] This invention relates to the field of mixing technology, and in particular to a magnetic material strong mixing device and mixing method. Background Technology

[0002] In the preparation of magnetic materials, it is usually necessary to fully mix magnetic powder with metal oxide powder before proceeding with subsequent processes such as sintering. Therefore, strong mixing equipment is required to mix magnetic powder and metal oxide.

[0003] Existing high-intensity mixing equipment directly pours magnetic powder and metal oxide powder into the mixing device during high-intensity mixing, and then performs high-intensity mixing through the high-speed rotation of the stirring rod in the mixing device. However, because magnetic powder is prone to adsorbing and forming clumps, when magnetic powder and metal oxide powder are added to the high-intensity mixing device, the magnetic powder adsorbs and becomes difficult for the metal oxide to mix into the magnetic powder during high-intensity mixing, which easily leads to poor mixing effect.

[0028] Among them, reference Figure 2 The magnetic powder feeding mechanism includes a suction ring cylinder 25, and a round hole is opened on the inner wall of the top of the mixing cylinder 1. A vertical cylinder 14 is slidably connected to the inner wall of the side of the round hole. The suction ring cylinder 25 is fixedly connected to the outer wall of the side of the vertical cylinder 14. The bottom end of the vertical cylinder 14 extends into the interior of the rotating cylinder 21, and the top end of the vertical cylinder 14 extends into the interior of the partition shell 8. A connecting rod 5 that slides inside the partition shell 8 is fixedly connected between the outer wall of the side of the vertical cylinder 14 and the top end of the lifting shell 38. An outer ring shell 13 for the up and down movement of the lifting shell 38 is fixedly connected to the outer wall of the side of the inner cylinder 12.

[0029] Among them, reference Figure 1 and Figure 3 The drive mechanism includes a drive motor 10 fixedly connected to the top outer wall of the partition 8. A motor housing 9 is provided on the outside of the drive motor 10. A threaded rod 6 is rotatably connected to the top inner wall of the partition 8. The bottom end of the threaded rod 6 is fixedly connected to the bottom inner wall of the rotating cylinder 21. The side inner wall of the vertical cylinder 14 is threadedly connected to the threaded rod 6.

[0030] Among them, reference Figure 2 The top outer wall of the storage cylinder 17 is hinged with four annularly distributed scrapers 15, and the four scrapers 15 form a conical cylindrical structure. The upper edge of the scraper 15 contacts the outer wall of the vertical cylinder 14. The side outer wall of the scraper 15 is fixedly connected with evenly distributed partition strips 26. The top of the side inner wall of the storage cylinder 17 is fixedly connected with a support frame 28. The side inner wall of the support frame 28 is fixedly connected with a scraper ring 29 located outside the vertical cylinder 14. An arc spring 27 is fixedly connected between the scraper 15 and the support frame 28.

[0031] Among them, reference Figure 4 The side of the partition 8 is fixedly connected to the feeding drive housing 11 located inside the magnetic powder storage chamber 7, and the top inner wall of the feeding drive housing 11 is rotatably connected to the feeding rod 31. The bottom end of the feeding rod 31 extends into the interior of the magnetic powder feeding pipe 4. The outer side wall of the feeding rod 31 is provided with a feeding spiral blade 32 adapted to the magnetic powder feeding pipe 4. The feeding rod 31 and the threaded rod 6 are connected by a belt to form a transmission.

[0032] In use, the present invention involves dispersing the raw magnetic powder into the magnetic powder storage chamber 7 and dispersing the metal oxide powder into the outer storage ring cylinder 16. The magnetic powder in the magnetic powder storage chamber 7 enters the storage cylinder 1 through the magnetic powder feeding pipe 4. The drive motor 10 drives the threaded rotating rod 6 to rotate reciprocally, which in turn drives the vertical cylinder 14 to move up and down reciprocally. When the vertical cylinder 14 moves to the bottom, the suction ring cylinder 25 moves to the bottom of the storage cylinder 17. At this time, the magnetic powder in the storage cylinder 17 will be attracted to the surface of the suction ring cylinder 25. Meanwhile, the lifting shell 38 is located at the bottom of the lifting ring cylinder 3. At this time, the metal oxide powder in the outer storage ring cylinder 16 will enter the lifting shell 38 through the discharge port 24 and the feeding port 23. Then, the vertical cylinder 14 moves upward. When the suction ring cylinder 25 passes the scraper ring 29, the scraper ring 29 will scrape the magnetic powder adsorbed by the suction ring cylinder 25 to prevent the suction ring cylinder 25 from adsorbing too much magnetic powder. Then, the magnetic powder adsorbed outside the suction ring cylinder 25 will push open the scraper 15 until the vertical cylinder 14 moves to the top. The suction cylinder 25 is located above the scraper 15, while the bottom of the lifting shell 38 is positioned to the side of the feed inlet 2. The metal oxide powder in the lifting shell 38 will be dispersed and fall into the mixing cylinder 1 through the feed inlet 2. When the lifting shell 38 moves upward, the elastic force of the compression spring 30 will compress the baffle ring 22 upward, causing the baffle ring 22 to be positioned to the side of the discharge inlet 24, preventing the metal oxide powder from entering the lifting cylinder 3 through the discharge inlet 24. Then the vertical cylinder 14 moves downward, and the scraper 15... The top of the scraper will scrape off the magnetic powder adsorbed on the surface of the suction ring cylinder 25. The scraped magnetic powder will slide down from the outer surface of the scraper 15 into the mixing cylinder 1 and mix with the metal oxide powder. The metal oxide powder and magnetic powder will be mixed by the rotation of the mixing rod 19. During the rotation of the threaded rotating rod 6, the feeding rotating rod 31 will be driven to rotate back and forth, which will drive the magnetic powder in the magnetic powder storage cavity 7 to enter the magnetic powder feeding pipe 4 intermittently, preventing the magnetic powder in the magnetic powder storage cavity 7 from adsorbing together and not falling.

The top of the side outer wall of the rotating cylinder (21) is fixedly connected with a turntable (34) located on one side of the protrusion (33), and the edge of the turntable (34) is fixedly connected with a ring-shaped extrusion rod (35).

8. A method for mixing magnetic materials, characterized in that, The method uses a magnetic material strong mixing device as described in claim 1. The steps are as follows: the raw material magnetic powder is dispersed and poured into the magnetic powder storage chamber (7), and the metal oxide powder is dispersed and poured into the outer storage ring cylinder (16); the magnetic powder in the magnetic powder storage chamber (7) enters the storage cylinder (17) through the magnetic powder feeding pipe (4), the driving mechanism drives the magnetic powder feeding mechanism to move and gradually add the magnetic powder in the storage cylinder (17) into the mixing cylinder (1), and at the same time, the outer feeding mechanism gradually adds the metal oxide powder in the outer storage ring cylinder (16) into the mixing cylinder (1); the rotating drum (21) rotates and drives the mixing rod (19) to rotate to mix the metal oxide powder and the magnetic powder.
